11This He said, and after that He said to them, "Our friend Lazarus has fallen asleep; but I go, so that I may awaken him out of sleep."
12The disciples then said to Him, "Lord, if he has fallen asleep, he will recover."
13Now Jesus had spoken of his death, but they thought that He was speaking of literal sleep.
14So Jesus then said to them plainly, "Lazarus is dead,
15and I am glad for your sakes that I was not there, so that you may believe; but let us go to him."
16Therefore Thomas, who is called Didymus, said to his fellow disciples, "Let us also go, so that we may die with Him."
asleep (v. 11) — Jesus is omnicient. He knew Lazarus was dead.
I was not there (v. 15) — If Jesus had been there, Lazarus wouldn't have died and the disciples wouldn't have learned the truth about the resurrection.
There is no record of anyone dying in Jesus presence or an any dead person in His presence staying dead. Even the thieves on the cross died after Him.
that we may die with Him (v. 16) — Thomas thought Jesus would be killed. Thomas had love but not faith.
